A new report from the Center on Juvenile and Criminal Justice adds to the growing body of evidence that legalizing or decriminalizing marijuana does not lead to any number of doomsday scenarios envisioned by legalization opponents. The report finds that "marijuana decriminalization in California has not resulted in harmful consequences for teenagers, such as increased crime, drug overdose, driving under the influence, or school dropout. In fact, California teenagers showed improvements in all risk areas after reform."
